export dwg hatch issue

[Anonymous]

Hello everyone, 

I have issue exporting revit (2017) to dwg, indeed some of my roof hacth didn't appear in my cad file...

It seems to be random, because for the same type of roof, some appear in Cad and other not..

Any Idea ?

Thanks in advance !

Hi,

Please accept our sincere apologies for the late, we have a backlog in the queue.

Before answering your question, I would like to double check one thing with you, since I didn't see any API related keywords or code snippets in your inquiring. Did you export those two DWGs via Revit API or just use Export function on the Revit UI? 

Cheers,
